Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a device for connecting adjacent unit furniture on the left and right when a plurality of unit furniture with movable shelves are arranged side by side on the left and right. It is something.

[Conventional technology]

In furniture for storing items, a base plate and a top plate of a fixed shelf formed in a box shape each protrude significantly forward, and a fixed shelf is placed between the forward protruding part of the base plate and the forward protruding part of the top plate. A movable shelf having approximately the same height dimension as the movable shelf is arranged, and the movable shelf is moved along the front surface of the fixed shelf via a rail provided on the upper surface of the protrusion of the base plate and the lower surface of the protrusion of the top plate. It has been well known in the past to be configured to be movable from side to side.

In order to accurately accommodate the size of the room and the amount of items to be stored, these storage furniture with movable shelves are made into units with fixed dimensions, and these unitized storage furniture (hereinafter referred to as ``unit furniture'') ) are arranged side by side on the left and right so that the ground rails and top rails of each unit furniture extend in a straight line, and by connecting adjacent unit furniture, one A movable shelf in one unit of furniture is configured to be movable relative to the other unit furniture.As an example, Japanese Utility Model Application No. 57-25650 as a prior art describes By cutting out each end of the base rail of the furniture, a rail non-laying part is formed on the left and right adjacent base plates respectively, a connecting rail is arranged in this rail non-laying part, and the connecting rail is connected to the left and right base plates. It is disclosed that it is fixed to each of the adjacent base plates with screws.

[The problem that the idea attempts to solve]

According to this prior art, since the connecting rail is fixed to each of the left and right adjacent base plates,
This connecting rail allows the height dimensions of the adjacent left and right base plates to be made the same, and has the advantage of allowing smooth movement of the movable shelf. Because it was troublesome to position the left and right base plates front and back so that they were in a straight line, there was a problem in that the connection work was time-consuming.

Furthermore, in the prior art, when a plurality of unit furnitures are connected to the left and right, the movable shelves in each unit furniture can be moved completely freely relative to the adjacent unit furniture. , the furniture is moved to the other unit of furniture even though there is no intention to move it to the other unit, or the movable shelf of one unit of furniture is strongly attached to the movable shelf of the other unit of furniture. There was also a problem in that the two movable shelves could be damaged or the stored items could fall over due to collision.

The present invention aims to solve these problems.

[Means to solve the problem]

In order to achieve this purpose, the present invention protrudes the top plate and the bottom plate of a box-shaped fixed shelf body forward by an appropriate dimension, and the lower surface of the forward-facing protrusion on the top plate and the upper surface of the forward-facing protrusion on the base plate. , a horizontally long groove extending left and right is carved along the front surface of the fixed shelf, and a support roller on the lower surface of the movable shelf disposed in front of the fixed shelf fits into the horizontally long groove of the base plate. A unit comprising a base rail having an upwardly U-shaped cross section is fitted, and a top rail having a downwardly U-shaped cross section into which a guide roller on the upper surface of the movable shelf is fitted is fitted into the horizontally long groove of the top plate. In the furniture, at least two of the fixed shelves are arranged side by side on the left and right so that the horizontally long grooves of the base plate and the horizontally long grooves of the top plate of both fixed shelves communicate with each other, and A rail non-laying part where the ground rail and the top rail are not fitted is formed at the ends of the grooves that communicate with each other, and between the upper surfaces of both base plates of the left and right fixed shelves, and between the upper surfaces of the left and right fixed shelves, Connecting plates are fixed between the lower surfaces of the top plates with screws, and on one side of both connecting plates,
A rail portion having a U-shaped cross section that fits into the non-rail laying portion of the horizontally long groove on the base plate and the top plate is bent and formed, and is engaged with either one of the connection plate for the base plate and the connection plate for the top plate. While holes are bored in the upper or lower surfaces of each of the movable shelves facing the engagement holes of the connecting plate, when the movable shelf moves to the ends of the left and right fixed shelves, the above-mentioned engagement holes are formed. The structure is such that the engaging ball that removably fits into the matching hole is biased to protrude.

(Operations and effects of the invention) With this configuration, each connecting plate is in close contact between the bottom surfaces of the top plates adjacent to the left and right, and between the bottom surfaces of the bottom plates adjacent to the left and right, so that the The top plates and the left and right base plates are connected on the same plane, the top rails and the ground rails of the left and right unit furniture are connected at the same height, and the rail portion formed on each connecting plate is
By fitting into each end of the horizontally adjacent horizontal grooves, the front and rear positions of the left and right top plates and the front and rear positions of the left and right bottom plates are automatically determined.

Furthermore, when the movable shelf moves to the end of each fixed shelf, the engagement balls provided on the top or bottom surface of the movable shelf engage with the engagement holes provided in the connecting plate against the biasing force. By doing so, the movable shelf can be temporarily stopped at the end of the fixed shelf, while if the movable shelf in the stopped state is pushed in the left and right direction with a certain amount of force, the engaging balls will move against the connecting plate. The movable shelf can be disengaged from the engagement hole and transferred to the adjacent unit furniture.

Therefore, according to the present invention, the longitudinal and height positions of the left and right unit furniture can be accurately and quickly positioned using the connecting plate for connecting the left and right unit furniture. This has the effect that the work of interconnecting them can be done quickly.

Furthermore, when transferring the movable shelf of one unit of furniture to the other unit of furniture, the movable shelf can be temporarily stopped, so there is no possibility of accidentally moving the movable shelf to the adjacent unit of furniture. This has the effect of reliably preventing a movable shelf from violently colliding with another movable shelf and damaging both movable shelves, or from overturning the stored articles.

Moreover, the engagement holes for temporarily stopping the movable shelf are drilled in the connection plate for connecting the left and right unit furniture, so even though the movable shelf is temporarily stopped, This makes it possible to avoid complicating the structure of the unit furniture as much as possible.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 indicates unit furniture that can be stacked up and down and connected left and right. A fixed shelf 3 with base plates 5'', 5' projecting largely forward, and a movable shelf 6 disposed between the protrusions of these top plates 5, 5'' and the protrusions of the base plates 5'', 5'. The left and right unit furniture 1 are arranged side by side so that the end faces of their top plates 5, 5'' and the end faces of their base plates 5'', 5' are in contact with each other. Reference numeral 2 is the underframe.

In addition, since the base plate 5'' of the unit furniture 1 located on the upper stage and the top plate 5'' of the unit furniture 1 located on the lower stage are used as a single board, in order to simplify the explanation, from now on, The plate indicated by the reference numeral 5'' is referred to as an intermediate top plate.The top plate 5, intermediate top plate 5'', and base plate 5' are removably fixed to the fixed shelf 3 with screws 4, 4, respectively. ing.

On the upper surface of each board 5' and each intermediate top plate 5'' of each unit furniture 1, two horizontally long grooves 9 extending left and right along the front surface of the fixed shelf 3 are bored. A top rail 7 having a downward U-shaped cross section is fixed to each of the grooves 9, and inside the top rail 7,
Guide rollers 12a and 12b rotatably provided on the top surface of the movable shelf 6 are rotatably inserted, while the top rail 7 and the top rail 7 are provided on the top surface of each plate 5' and the top surface of the intermediate top plate 5''. Two horizontally long grooves 10 are carved so as to face each other, and a ground rail 8 having an upwardly U-shaped cross section is fitted into these. A rotatably supported support roller 11 is inserted, and thereby each movable shelf 6 cannot fall back and forth, but can move left and right along the front surface of the fixed shelf 3.

Reference numeral 1 among the guide rollers 12a and 12b
2a is a horizontal axis type, and 12b is a vertical axis type, but only one type may be used.

Of the movable shelves 6 provided in each of the unit furniture 1, the movable shelf 6 in the unit furniture 1 located at the lower left has its front and back depth dimension equal to the protrusion dimension of the intermediate top plate 5'' and the base plate 5'. The movable shelves 6 are formed to have approximately the same dimensions as the above, and only one movable shelf 6 is used, while the other movable shelves 6 are thinly formed and arranged in two rows, front and rear.

By cutting both ends of each of the top rails 7 and the ground rails 8 by a slight dimension (1), a top rail 7 is attached to each of the ends of the connection points in the horizontally long grooves 9 and 10 that communicate with each other from side to side. Toji rail 8
and form a rail non-laying part where it is not fitted,
Rail portions 16 formed on connecting plates 14, 14', which will be described in detail later, are fitted into these rail non-laying portions,
On the other hand, stoppers 23 and 24 for the support rollers 11 and guide rollers 12a and 12b of the movable shelf 6 are installed in the non-rail laid parts exposed to the outside in each of the horizontally long grooves 9 and 10 using embedded nuts 13 and 1.
It is screwed through 3'.

The connecting plates 14, 14' are connected to two adjacent left and right
The connecting plates 14, 1 have an appropriate area that extends between the top plate 5, the intermediate top plate 5'', and the base plate 2.
4' is fixed to each of the left and right adjacent top plate 5, intermediate top plate 5'', and base plate 5' with screws 20, and the top rail 7 is fixed to one side of the connecting plates 14, 14'. Alternatively, a rail portion 16 having the same cross-sectional shape as the ground rail 8 and twice the length dimension (1) of the end portions of the top rail 7 and the ground rail 8 is formed, and the rail portion 16 is Horizontal groove 9,
10, and screws 15, 19 are fixed to the top plate 5, intermediate top plate 5'', and bottom plate 5', respectively, via embedded nuts 13, 13'.

Then, as shown in FIG. 10, an engagement ball 21 is attached to the left and right ends of the lower surface of the movable shelf 6 so as not to fall off, and the engagement ball 21 is biased downward by a spring 22. On the upper surface of the intermediate top plate 5'' and the connecting plate 14' fixed to the upper surface of the base plate 5', upwardly bulging portions 17 having a height of 2 are formed with flattened upper surfaces, respectively. Each upwardly bulging portion 17 has the engaging ball 21 when the movable shelf 6 moves to the end of each fixed shelf 3.
An engagement hole 18 is formed into which the holder is removably engaged.

In the above configuration, each top rail 7 and bottom rail 8 in the left and right unit furniture 1, and the connecting plate 1
Since the rail portions 16 of the shelves 4 and 14' are connected in a straight line, the movable shelf 6 can be freely moved from one unit furniture 1 to the other unit furniture 1 adjacent thereto.

In this case, the connecting plate 1 connects the left and right fixed shelves 1 with each other.
4, 14', the connecting plate 14,
14′ is the top plate 5 adjacent to the left and right, the intermediate top plate 5″,
Since the base plates 5' are in close contact with each other, the left and right adjacent top plates 5, intermediate top plate 5'', and base plate 5' are connected so as to form the same plane, while the connecting plates 14, 14' By fitting the rail portion 16 between the left and right oblong grooves 9 and 10, the front and back positions of the left and right adjacent top plate 5, intermediate top plate 5'', and base plate 5' are automatically determined. from,
The unit furniture 1 arranged side by side on the left and right can be quickly connected to each other.

Furthermore, when the movable shelf 6 moves to the end of each unit furniture 1, the engagement balls 21 provided on the lower surface of the movable shelf 6 engage with the engagement holes 18 in the connecting plate 14'. Since the movable shelf 6 temporarily stops at the left and right ends of each unit furniture 1, it is possible to move the movable shelf 6 too much, or cause the movable shelf 6 that has been moved to collide with another movable shelf 6 that is stopped. It is possible to reliably prevent the movable shelves 6 from being damaged or the articles stored on the movable shelves 6 toppling over due to collision.

In this case, if the connecting plates 14, 14' are formed with a bulge 17 and the engagement hole 18 is bored therein, the engagement can be made without increasing the thickness of the connecting plates 14, 14'. There is an advantage that the ball 21 can be reliably engaged.

The engagement ball 21 is provided on the upper surface of the movable shelf 6, and a bulge 17 and an engagement hole 18 are formed in the connecting plate 14 for the lower surface of the top plate 5 and the lower surface of the intermediate top plate 5''. It is okay to do so.
